Problems setting up image gallery

I hope this is the right place to post this - I am new with silverstripe and this site, so please bear with me.

I have been trying to setup an image gallery, and have installed dataobject_manager, image_gallery, and uploadify (from different sources, finally doing a svn checkout from http://carlinowebdesign.svn.beanstalkapp.com/modules/trunk/ ), by copying all three dirs into my silverstripe root-dir and running /dev/build, followed by flushing the cache.
I think that setting up a gallery would then comprise the following steps:
- create a new image gallery page
- create a new album
- upload photos into that album
It is the third step I cannot achieve - the dialogue looks strange, the upload button is hidden behind the entry field for the search path - this not only happens on my installation (ubuntu server, win7/current FF, also IE8 and GC), but also when I try the same with http://dataobjectmanager.carlinowebdesign.com/admin/cms/ - I am unable to upload photos using that dialogue. I also don't succeed in viewing photos I uploaded via the files&images tab - I am stumped.

Is there a problem with my assumptions? Or should this work like that and there is a bug somewhere?

I'd be happy for any input in that matter, and willing to invest some time to get that problem resolved.

cool, works now, thx! :) I'll dig through your blog some more to get more familiar with how this works, thx for your work on this!

Next, I'll try to put a carousel into a page which would be fed from an album - if anyone has any ideas on this, maybe together with a recommendation on a non-flash carousel showing, as a horizontal slider, multiple images (e.g. http://css-tricks.com/examples/MovingBoxes/ does a lot of what I want - I don't need the zooming, though...) - I am all ears! :)
